Not only will be it be National Chocolate Ice Cream Day, it is also going to be the 12th edition of That Dam TT!

Maybe we can have some ice cream available while we await the results this year.

Thanks to everyone that registered. 137 isn't a record but it's pretty close to our largest race ever, and when races are seeing smaller turnouts it's appreciated!

Start times will be emailed out and posted closer to noon. They have to be generated and then agreed by USA Cycling, and everyone involves has a real job as well. Please be patient with us. Thanks.
